stratospheric
Polar regions are not actually devoid but have small concentrations of the ozone layer which is a protective layer present in the stratospheric region of earth and which helps in the absorption of the harmful UV radiations coming from the sun. The reason is a pretty obvious one that the CFC's which are used by the mankind for their good are carried towards the poles by polar stratospheric winds which in turn move in the stratospheric region due to the high pressure. These CFC's hinder the rate of formation of ozone thus causing depletion or what we mention as an "ozone hole".
The exosphere is the atmospheric layer that is the furthest from Earth's surface. It extends from about 500 km to 10,000 km above sea level.
The topmost atmospheric layer is called the exosphere. This layer extends from about 500 kilometers (310 miles) above the surface of the Earth to the edge of space, around 10,000 kilometers (6,200 miles) up.
The troposphere is the closest to the Earth and most dense atmospheric layer
The thickest layer of the atmosphere is the troposphere, which is located closest to the Earth's surface. It extends up to about 10-15 kilometers above sea level and contains the majority of the Earth's atmospheric gases.
stratosphereThe atmospheric layer above the troposphere is the stratosphere. It extends to about 30-35 miles above the earth's surface, and is the most stable layer.

The stratosphere is right above the troposphere, which is what we live in. The ozone layer exists within the stratosphere. It extends up to about 50km above the surface.
mesosphere
The exosphere is the atmospheric layer that is the furthest from Earth's surface. It extends from about 500 km to 10,000 km above sea level.
The atmospheric layer below the mesosphere is called the stratosphere. It is located above the troposphere and below the mesosphere, and it contains the ozone layer which absorbs and scatters the sun's ultraviolet radiation.
The lowest atmospheric layer that contains greenhouse gases is the troposphere
An atmospheric layer that contains layer is stratosphere. It contains ozone layer.
The topmost atmospheric layer is called the exosphere. This layer extends from about 500 kilometers (310 miles) above the surface of the Earth to the edge of space, around 10,000 kilometers (6,200 miles) up.
stratosphereThe atmospheric layer above the troposphere is the stratosphere. It extends to about 30-35 miles above the earth's surface, and is the most stable layer.
The atmospheric layer that is at 50 to 85 km above the Earth's surface is the mesosphere. It is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere. The mesosphere is characterized by decreasing temperatures with increasing altitude and is where most meteorites burn up upon entering the Earth's atmosphere.
The thermosphere does not extend above the polar regions. This layer of the atmosphere is known for its high temperatures due to absorption of solar radiation and recombination of ions and neutral particles. Above the poles, the thermosphere merges into the exosphere, the outermost layer of the atmosphere.
